Hanna 4-1 tester the cheapest I seen

[Zandor]

Yeah the calibration solutions(4.01,7.01,10.1) are included FREE through this company. Do you feel this is a great deal and perfect for a newbie to hydro?

You should have the 4.01, 7.01 and then one for the TDS calibration 1413uS/cm. You can use the 4.01 as storage solution.

There is no need for the 10.01 solution the unit is designed to work with the 2 point set 4.01 & 7.01 for the Ph calibration.

Yes it is a very good price for that unit.
